# Token Quote vs Received Amount — Rolling Mean Report

> Token Quote vs Received Amount — Rolling Mean Report is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).

Computes a rolling mean of token quote shortfall (quoted minus received token amounts) over a sliding window across a series of observations.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability token-quote-vs-received-amount-rolling-mean-report-c2230bf7 -d '<json body>'
```

Example prompt: Can you run a rolling mean report on these 4 token trade observations — quoted 1000 received 980, quoted 1100 received 1078, quoted 1000 received 980, quoted 1100 received 1078 — using a window of 2 to see the average shortfall trend?

## When to prefer this

Choose this endpoint when you have a time-series of token trade observations and need to smooth out noise using a rolling mean to identify systematic shortfall trends, rather than inspecting raw per-trade differences. It is ideal for auditing broker or DEX fill quality over a batch of trades rather than evaluating a single transaction.

## Known failure modes

- Fewer than 2 rows supplied — minimum row count not met
- Window size exceeds number of rows — invalid window configuration
- quoted_tokens or received_tokens missing or zero — required fields absent
- Values exceed maximum threshold (1e16) — out-of-range inputs rejected
- Non-numeric values in numeric fields — type validation failure

## How this service works

Token quote versus received amount — Rolling mean report: Rolling mean report for Token quote versus received amount. Supplied token observations only. Deterministic calculation or caller-threshold verdict, not a live scan, safety proof or trade recommendation. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded rolling mean report report.

## Output

Returns a rolling mean report showing the average difference between quoted_tokens and received_tokens across a sliding window of the specified size. Each windowed segment yields a mean shortfall value, enabling trend analysis of token delivery accuracy across the supplied observations.
